title: Arthroscopic treatment of ulnar impaction syndrome.
abstract: Ulnar impaction syndrome occurs in the setting of a central traumatic or degenerative defect in the triangular fibrocartilage complex in patients with ulnar positive variance. Chondral and subchondral edema, mechanical impingement of the articular disc, and chondromalacia of the distal ulna, proximal lunate, and proximal triquetrum produce symptoms with activity that do not improve with rest. Decreasing ulnocarpal load-sharing across the wrist with recession of the distal ulna is necessary to relieve symptoms in the majority of patients. Arthroscopic treatment with triangular fibrocartilage complex debridement and arthroscopic ulnar wafer resection is an effective treatment for ulnar impaction syndrome. It affords a single-stage, minimally invasive approach, with similar efficacy and fewer complications than open wafer resection or ulnar shortening osteotomy.
